File folder with individual holding units

ABSTRACT

A file folder includes a rail member fixed to the connection portion of the file folder and the rail member includes a plurality of ribs extending from a surface thereof so as to define grooves between the ribs. The grooves communicate with openings in a top end and a lower end of the rail member. Each rib has a head on a distal end thereof and the head is wider than a width of the rib so as to form a narrow entrance corresponding to each groove. A holding unit has an elongate insertion which includes an enlarged ridge on a side thereof so as to be slidably inserted into the grooves via the openings and the insertion is sized to be slidably engaged with the narrow entrance. Document is positioned or collected by the holding unit.

FIELD OF THE INVENTION

The present invention relates to a file folder with individual holdingunits which are slidably connected to the file folder and can be removedfrom the folder individually.

BACKGROUND OF THE INVENTION

A conventional file folder generally includes a front cover, a backcover and a connection portion which connects the front cover and theback cover side by side. Document is received between the front and backcovers. However, the document easily slips out from the file folder sothat some manufacturers install plastic pockets to the file folder andthe document can be received in the pockets. When using the document,the user has to pull the document from the pockets and the sheets of thedocument are not well positioned and easily blown away. After thedocument is used, the sheets have to be organized and put into thepocket and this may require a lot of time.

The present invention intends to provide a file folder which includesindividual file holding units which are able to be removed from the filefolder individually and to collect the sheets of document by fasteners.

SUMMARY OF THE INVENTION

The present invention relates to a file folder which comprises a frontcover, a back cover and a connection portion which is connected betweentwo ends of the front cover and the back cover. A rail member is fixedto the connection portion and includes a plurality of ribs extendingfrom a surface thereof so as to define grooves between the ribs. Thegrooves communicate with openings in a top end and a lower end of therail member. Each rib has a head on a distal end thereof and the head iswider than a width of the rib so as to form a narrow entrancecorresponding to each groove. A holding unit has an elongate insertionwhich includes an enlarged ridge on a side thereof and the enlargedridge is sized to be entered into the opening and the insertion is sizedto be slidably engaged with the narrow entrance.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 4, the file folder 1 of the present inventioncomprises a front cover 11, a back cover 12 and a connection portion 13which is connected between two ends of the front cover 11 and the backcover 12. A rail member 2 is fixed to the connection portion 13 byrivets and includes a plurality of ribs 22 extending from a surfacethereof. Grooves are defined axially in the rail member 2 by the ribs 22and communicate with openings 23 in a top end and a lower end of therail member 2. Each rib 22 has at least a head 221 on a distal endthereof and the head 221 is wider than a width of the rib 22 so as toform a narrow entrance 21 corresponding to each groove.

A holding unit includes an elongate insertion 3 and two side plates 32,wherein an enlarged ridge 31 is formed on a side thereof an the two sideplates 32 extend from the other side of the insertion 3. The two sideplates 32 are flexible and can be pivoted toward each other as shown inFIGS. 3 and 4. The enlarged ridge 31 is sized to be entered into theopening 23 and the insertion 3 is sized to be slidably engaged with thenarrow entrance 21. The enlarged ridge 31 of the insertion 3 is thenstopped by the heads 221 on the ribs 22 and the holding unit cannot beseparated from the rail member 2 via the narrow entrance 21. A pluralityof first fasteners 321 and second fasteners 322 are located on the twoside plates 32 respectively. In this embodiment, each of the firstfasteners 321 is a protrusion and each of the second fasteners 322 is atubular member in which the protrusion is removably inserted.

Document composed of sheets 4 are located between the two side plates 32and the first fasteners 321 extend through holes in the sheets 4 and areengaged with the second fasteners 322 to position the sheets 4. Theholding unit is connected to the rail member 2 by inserting the enlargedridge 31 into the groove via the opening 23 in either the top end of thelower end of the rail member 2. The user can remove the holding unitsindividually from the rail member 2.

FIG. 5 shows another embodiment of the file folder wherein the holdingunit does not have the side plates 32 as shown in the previousembodiment and a plurality of plastic pockets 33 are connected to theother side of the insertion 3. Sheets 4 can be collected in the plasticpockets 33.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the, scope of thepresent invention.

1. A file folder comprising: a front cover, a back cover and aconnection portion connected between two ends of the front cover and theback cover; a rail member fixed to the connection portion and includinga plurality of ribs extending from a surface thereof, grooves definedaxially in the rail member by the ribs, the grooves communicating withopenings in a top end and a lower end of the rail member, each ribhaving at least a head on a distal end thereof and the head being widerthan a width of the rib so as to form a narrow entrance corresponding toeach groove, and a holding unit having an elongate insertion whichincludes an enlarged ridge on a side thereof, the enlarged ridge beingsized to be entered into the opening and the insertion being sized to beslidably engaged with the narrow entrance.
